PHP with Informix IDS support via IFX Module – Centos5 / RHEL5 12 June 2007

Posted by Maulvi Bakar in : Linux, Work , 1 comment so far

Hello everyone, sorry for the long silence..

These are drafts mainly, careful with the syntax until I fix the coding code of my wordpress.. :-P
Firstly, install the Informix Client SDK for Linux..
Get the Client SDK from here – http://www-306.ibm.com/software/data/informix/linux/csdk.html

Download, untar it to a folder, then follow the instructions below -

# useradd informix
# passwd informix

./installclientsdk

install to /opt/IBM/informix

ensure “/etc/hosts” have these entry -

x.x.x.x informix_server_hostname

ensure that “/opt/IBM/informix/etc/sqlhost” have these entry -

database_instance_name onsoctcp informix_server_hostname 9088

add these at line number 38 in file “/etc/init.d/httpd”, which should be before the “# check for 1.3 configuration” line -

export INFORMIXDIR=/opt/IBM/informix
export INFORMIXSERVER=mtx2informix_prod
export ONCONFIG=onconfig
export PATH=$PATH:$INFORMIXDIR/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$INFORMIXDIR/lib:$INFORMIXDIR/lib/esql

Download this -

http://ftp.redhat.com/pub/redhat/linux/enterprise/5Server/en/os/SRPMS/php-5.1.6-5.el5.src.rpm

and install it

rpm -ivh php-5.1.6-5.el5.src.rpm

go to /usr/src/redhat/SPECS/

edit the php.spec file at line 428 (approximately after the xml, before $*, add this line -

–with-informix=/opt/IBM/informix \

Then, run this command -

rpmbuild -ba php.spec

and also, prior to rebuilding the RPM, may need to export the environments -

export INFORMIXDIR=/opt/IBM/informix
export INFORMIXSERVER=mtx2informix_prod
export ONCONFIG=onconfig
export PATH=$PATH:$INFORMIXDIR/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$INFORMIXDIR/lib:$INFORMIXDIR/lib/esql

Run this command to identify whatever php packages that you’ve installed -

rpm -qa | grep php

uninstall them using this command

rpm -e package_name1 package_name2

and re-install them using newly recompiled RPMs from this location -

“/usr/src/redhat/RPMS/i386/”

May need to use “–nodeps” option – the .so files required are actually Informix libraries already found within the ld_library_lib path

Hope it is useful to someone else someday ;-)
